> KeyFieldBasedComparator and KeyFieldBasedPartitioner are libraries so should not appear
as getters and setters in JobConf. For the new API there are getters and setters on KeyFieldBasedComparator
and KeyFieldBasedPartitioner themselves - we should add the equivalent to the old API and
deprecate the references in JobConf.
